Obstacles and ways to increase yield of pomegranate

Insect damage, frost and so on. To put forward measures for the corresponding cultivation techniques 7. l excellent selection of new varieties of pomegranate in Henan Province by the author and all the staff Study Group, after nearly a decade of efforts, breeding new varieties of pomegranate pomegranate Yu 1, 2, Yu pomegranate, pomegranate Yu 3, respectively, compared with the control ( where old varieties) increase by 122.4%, 129.3%, 72.4%, 6 years old the largest tree fruit weight, respectively 672,850,[link widoczny dla zalogowanych],536 g. Quality, appearance, resistance and other traits are better than control. Three species in August 1995 in Gongyi City Nanhe Duzhen through the identification, were awarded the 1996 Forestry Department of Henan Province, the provincial agricultural system, the second prize and third prize in Henan Branch Zhu,[link widoczny dla zalogowanych], present. Is to promote the use of barrier province. 2 deep plowing soil improvement Megranate deep in the construction of integrated soil improvement is necessary before the park was built after the park or the expansion of deep plot points, improve the soil. Deep plowing depth of 80 ~ 100era appropriate, and the Base Fertilizers can be combined. In Orchard 2 to 3 years after completion. 3 facilities adequate enough fertilizer fertilizer, year after year can yield pomegranate. According to the research,[link widoczny dla zalogowanych], production of lkg per pomegranates, about 2kg of quality organic fertilizer and 0.1 ~ 02kg fertilizer (N, P, K, etc.), local experience and according to the situation of local reference use. Fertilization can be basal, top dressing, Yemianpenfei other methods. 4 to maintain soil moisture, drought Taiwan proper drainage of water, is not only a high yield security. Freezing to prevent cracking and also plays an important role. According to our practice that: high and stable yield of Megranate. Soil moisture content maintained at 60% or so. 5 Wang and flower the first fruits of control of the first 2 to 4 years old saplings easily flourishing. Pina flourishing control measures are: (1) scientific fertilization, note that N, P, K and trace elements in the mix. (2) control of water. (3), excessive tree sprouting from the trunk before digging around 80era wide 20era,[link widoczny dla zalogowanych], 30cm deep ditch cut off part of the root system. (4) to reduce the number of the trunk. To go it alone to stay in a dry plastic surgery, and to do more to stay 4 shaping up to dry. The excess removed, and to promptly opened around three dry point, as a first layer of the main branch used to do to stay dry in the middle of a dry culture. (5) increase the angle. Main branch point should have 60 to 70 ', down branches, the result should have a branch in the 80 ~ 90'. Enough time point position correlation. (6) back in time to erect branches sparse. (7) by girdling, girdling Zhu Wang operation control. One under 56 may be a degree of flourishing. The ringing or girdling. Ringing the width of the branch diameter is 1 / '10 is appropriate. (8) Chemical control of Wang. With MET. In early April to late May soil application. Qi Shi per plant were effective 1 ~ 15g. Also available in 5 to 7 months. 15% of the tree spraying MET 1000 ~ 2000 �� 10 (ppm) solution. 6 Open the optical bore depression caused by the way of the reasons. Branches mostly erect more than the total branch volume. Therefore, to first go to wang long sparse erect branches, pest-free fruit branches and lower branches drooping skirt, then, if the branch volume is also large, then retraction, or cutting back the growth of long branches and thin branches cross. After thinning the canopy light transmission rate under the Efficiency in Tobacco Fields 20 - 30% is appropriate. 7 Paul Park flowers and fruits should be built with the grant review and selection of varieties with high fruit pomegranate varieties such as Yu 1, 2, 3, and so on. Flower thinning can be taken (pistil abortion bell shaped flowers) Thinning (7 months after the fruit), flowers before the ringing or girdling, spraying 02% ~ 0.3% of borax or boric acid, flowering Fang Feng, artificial pollination, after flower spray gibberellic 500 �� 10 cable and other measures. Have a role. 8 to prevent fruit cracking a fundamental measure to prevent cracking, moisture is evenly distributed. Not fluctuating. Do when the ship poured dry. When flood discharge. 6 July fruit enlargement of one of the keys to prevent cracking, not water; picking fruit cracking prior to the picking of the time, 500 �� 10 of the GA can spray the solution on fruit, has a good effect. 9, pest control dry rot, the tree commonly used method is to spray Bordeaux mixture, lime sulfur, carbendazim and so on. Trunk smear 990A, Fumei arsenic. The most fundamental way is to use resistant varieties, the new pomegranate breeding Yu 1, 2, 3, new varieties, the incidence of dry rot index 17l4%, 1667%, 15.20%. 25.17% lower than the control, 75.92%, 7739%. Hazard prevention and control of pests bud. Should be conducted early after germination. On the prevention and treatment DICHOCROCIS. Spraying can be used, plug the mouth, ride leaves, bagging, fruit and other measures to put off the insects. 1O prevent freezing frost damage prevention. The key measures are used to maintain robust cold varieties and tree vigor. In addition In addition, post-control water control fat. Spray CEPA, applied paclobutrazol, before winter white-, earth, water, frozen water and other measures are effective. This article was received 19,971 BU 29
